Chinese web pages have featured photos of a new variant of the Chengdu Aircraft Corporation (CAC) J-10 multirole fighter that appear to confirm a spate of late December 2008 web reports on this same aircraft, with some accounts noting it has already been test flown.

This single-seat variant differs from the initial single-seat J-10 model in that it appears to feature a revised engine inlet, consistent in design with the diverter-less supersonic inlet (DSI) featured on the latest version of the Chengdu FC-1 lightweight multirole fighter. Reminiscent of the DSI modification first tested on a Lockheed Martin F-16 Block 30 in 1996, this modification saves weight and improves specific engine power and stealth. It also cleans up the J-10's previous complex inlet configuration, which was reportedly prone to vibration.

China's research on DSIs dates back to the late 1990s, with Chengdu's 611 institute for aerospace design having been assisted by government-funded research at the Nanjing University of Aeronautics and Astronautics.

a fighter plane is good in its own right,j-10/fc20 can be a good plane but until it proves itself it is a no match for the flankers, which is a proven plane worldwide and used by 30 odd countries.
battles are not fought by adobe photoshop generated planes.which is most often the case for chinese planes.

Serious Wake up call for IAF, better it should get its act in order by ramping up a production of LCA. Since even MRCA is not an answer for J-10B as their huge numbers will be a biggest constraint. Only large number of a LCA is the only answer.

Anybody who can through light on the aerodynamic performance of J-10? its airframe looks like that of the EF Typhoon but with a single engine and EF Typhoon is said to have a great aerodynamic performance.

Look care fully there is a design difference in the engine intakes of the lavi and the J-10S , which is not to say that the Chinese did not copy the LAVI we all know they did.
